BUILD FAILED (exit value 2, total time: 2s)

The 1st error looks simple. What did you try (to fix that first error)? i.e. can you clarify your problem ... (perhaps they are simple typo's) — 2785528

it seems you are using the compiler for cygwin, while you should use the cross compiler cygwin2windows sourceware.org/ml/cygwin-announce/2018-07/msg00010.html — matzeri

i find the solution of my problem. because GCC doesn't have a __int64 built-in, and this patch basically uses "long long" instead we must edit edit the file /include/win32/jni_md.h, Where is the installation root (eg., c:/jdk1.4.2). replace the code

typedef long jint;
typedef __int64 jlong;
typedef signed char jbyte;

with

typedef long jint;
#ifdef __GNUC__
typedef long long jlong;
#else
typedef __int64 jlong;
#endif
typedef signed char jbyte;
